Blahtech GL is our gamma-levels indicator. It does two things differently from every other GEX tool out there.
First, it filters. Most GEX tools plot every strike with open interest — your chart ends up covered in lines that don't actually mean anything. Blahtech GL only marks the strikes where options pricing itself is showing something unusual: real positioning anomalies, not just paper inventory sitting on the books.
The indicator marks four kinds of level:
Mega / moderate / weak calls — three tiers of upside strikes ranked by how dominant the call positioning is. Mega calls are the heavyweight overhead levels; moderate and weak calls are secondary and tertiary levels worth knowing about but not betting the farm on.
Mega / moderate / weak puts — the same tiered ranking on the downside.
Gamma walls — the standout strikes where positioning is concentrated heavily enough to dominate hedging flow regardless of which side they're on.
Gamma flip — the price level where the overall hedging regime transitions. Above it, dealer hedging tends to dampen moves; below it, it tends to amplify them.
What the indicator does NOT do is tell you whether a level will act as a magnet, a reversal point, or an accelerator on a given day — that's a function of vol regime, time-of-day, and the context.
